Textile machinery giant Jingwei Textile Machinery on Monday posted a 69.1 per cent leap in first half net profit to 84.6 million yuan (US$10.4m) from 50 million yuan in the year-ago period.

The company said domestic sales for the six month period almost doubled to 2.09 billion yuan from 1.1 billion yuan last year as its results were boosted by the acquisition of two textile machinery companies.

It added its gross profit margin slipped two percentage points due to the rising cost of raw materials.
